When you use any of the shapes available in PowerPoint, you are not limited
to what their default appearance looks like. You may want to change
a rectangle to a rhombus, or even edit a curved or freeform line differently.
The good news is that you can do this by using the Edit Points option
-- this almost makes PowerPoint a drawing program that provides you
the option to play with vertexes (points), handles, etc. -- very similar
to what you would do in Adobe Illustrator or CorelDRAW.

A vertex is a point within the outline of any shape that can be
dragged or edited to change the appearance of the shape. A vertex is
indicated by a small black square (you can see five of these black
squares in Figure
1). Note that you will learn more about how to get to this
Edit Points interface later in this tutorial -- meanwhile also notice
that when you select a vertex, one or two blue handles appear -- these handles
end with transparent squares -- these transparent squares have black
outlines and can be dragged to reorient the structure of the selected
shape.

Also in PowerPoint, the terms vertex and point are often used interchangeably.

Follow these steps to get to the Edit Points mode for any shape (rectangle,
line, drawn shape, etc.) in PowerPoint 2010:

Select the drawing so that the Ribbon area now shows the Drawing
Tools Format tab, as shown in Figure 2. Activate
this Ribbon tab by clicking on it.

Note: The Drawing Tools Format tab is a contextual
tab. These tabs are special tabs in the Ribbon that
are not visible all the time -- they only make an appearance
when you are working with a particular slide object which
can be edited using special options.

From the Drawing Tools Format tab, locate the Insert Shapes group.
Then click the Edit Shape button (highlighted in red, in Figure
2 above) to view a drop-down
gallery that you can see in Figure 3. And from this
drop-down list, choose the Edit Points option (refer
to Figure
3 again).

Tip: Is the Edit Points option grayed out?
Some shapes, especially a straight point-to-point line will
not allow you to choose the Edit Points.

A number of small black squared points will appear on the outline of
the shape, as shown in Figure 4. These points are known
as vertexes, which mark any point in your shape that denotes an extremity
of a curve or line segment, or even the start and end point of an
open shape.

Figure 4: Vertexes appearing on the drawing

Place the cursor on any of the vertexes - the cursor will change to
a small rectangle with four directional arrows around it, as you can
see in Figure 5.

arrows

Now click on the vertex to select it, and reposition the vertex by
dragging it to a new position. A black dashed line
appears showing the changes to the shape that you are making, as
shown in Figure
6.

You can also change how the shape looks without repositioning the
vertex. A selected vertex shows one or two blue
handles (lines emanating from the vertex), as shown in Figure
7.
To alter the degree of the curve or line on either sides of the vertex
in relation to the next vertex along the line, just click on one
of the handles and drag them to reorient the line's structure (refer
to Figure
7 again).
